V IMPROVEMENT lN GANG-PLOWS.

Specification forming part of Letters Patent No. 45,897, dated January10, 1865.

To all whom it may concern:

Be it known that I, THOMAS SHORT, of Fairmount, in the county ofVermillion and State of Illinois, have invented a new and usefulImprovement in Gang-Flows; and I do hereby declare the following to-be afull and exact description of the same, reference being had to theaccompanying drawings, making part of this specification, in which--Figure 1 is a plan of a gang-plow illnstrat ing my invention, and Fig. 2is a side elevation of the same.

Similar letters of reference indicate corresponding parts in the twofigures.

The object ofthis invention is to provide novel and simple means tofacilitate the vertical and lateral adjustment of the plows in orderthat the driver may suspend the plowing operation or avoid obstacleswhich might offer such resistance to the plows as to break orinjure thesame, as will be hereinafter fully explained.

In order that others skilled in the art to which my invention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe its construction and operation.

In the accompanying drawings, A A A represent the various parts of themain supporting-frame, which, by means of short shafts a a, is mountedupon the carrying-wheels B B.

0 represents a frame which may serve to connect the rear ends of thebeams A A, and which has secured upon itthe drivers seat D.

G is a frame similar in form to the frame 0, and erected at a point alittle forward of the transverse center of the machine.

E representsaplow-beam, into which are securely inserted the stocksfofthe plowsF F, and which occupies a position, between the beams AA, asshown clearlyin Fig.1. Atits rear end the beamE hasno other supportthanthat afiorded by the plow F, but at itsforward end the beam E isattached to the main frame of the machine by a double-crank rod, Gr,which passes through elevises e e, which embrace and are bolted to theforward end of the beam E. The respective ends of the rod G arehook-shaped, which adapts them to be secured in staples a a near theforward ends of the beams A A. The rod G has full room or space withinthe staples a a and clevises e 6, so that it may readily turn therein.

H is a lever, fulcrumed at h upon the frame 0, and connecting with therod Gr through the medium of a link or fod, h. This lever H, extendingbackward to a point in suitable proximity with the'seat D, enables thedriver at a moments notice to elevate the beam, and thereby turn thepoints of the plows in an upward direction, to do which it is onlynecessary to depress the free end of the lever H. When the lever is thusdepressed the rear end ofthe beam E is supported by the plow F, whoseheel moves in contact with the ground. The free or hand end of the leverH is so much longer than the acting end thatlittle strength need bebrought into requisition to elevate the beam. The central portion of therod H is made straight or in conformity with the forward end of the beamE; but the portions of said rod which extend beyond the sides ofthe beamE aredefiected in such manner that no abutment is presented which mightcome in contact with the clevises c e, and thereby in tercept orinterfere with the upward movement of the beam E.

1 is a post rising from the beam E and between the frames OO. Bygrasping this post with his hand the driver may adjust the rear end ofthe beam and the plow afiixed thereto with facility, theforward end ofthe beam,with its plow, being capable of lateral adjustment by the leverH.

Having thus described my invention,the following is what I claim as newtherein and desire to secure by Letters Patent:

The arrangementofthe double-crank-shaped connecting-rod G, clevises 0e,links a a',beam E, lever H, and post I, the whole being employed forjoint operation in the manner and for the purpose specified.

The above specification of my improved gang-plow signed this 20th day ofJune, 1864.

THOMAS SHORT.
